Raw Sienna

Royal Talens Gouache is made with a unique dextrin-based binder that sets it apart from most other brands of gouache. This traditional formulation becomes more fluid as it is mixed, allowing you to cover large areas more evenly without dragging. It's also an incredible value.

Properties

Brown Ochre provides artists with earthtones from cream to brown and is a dull, dark variety of Yellow Ochre. Its transparency varies widely from opaque shades to more transparent ones, which are valued for their use as glazes. It has good hiding power, produces a quick drying paint, and can be safely mixed with other pigments. The highest quality Brown Ochre comes from Cyprus, where it is yellow in its raw form and is roasted to get the deeper brown-red varieties that result when water is removed. (See Yellow Ochre, PY42/43.)

Permanence

Brown Ochre has excellent permanence.

Toxicity

Brown Ochre is non-toxic.

History

Ochre comes from the Greek word ochros, meaning pale yellow. It has been used since prehistoric times, and evidence of its use has been found in some of the earliest known cave paintings in Lascaux, France. It has also been called Goethite, after the German philosopher and mineralogist Johann Wolfgang von Goethe (1749-1832).
